Hey I was trying to use the demo version of cdma workshop my problem is it shows com port 19 as free and that one is only usable in the registered version. So I manually change the com port on my computer to com port 1 also tried com 2 these were the only ones not showing as busy on my computer but then back on cdma workshop it was still showing up as busy so any suggestions on how to get around to change my prl would be greatly appreciated.
